"SELF-CLOSING FAUGET.

EPZEICIFICATION forming part; of Letters Pjaterlt No. 322,114, dated July 14, 1885.

' Application fnd May 14 1985. (No model.)

To all who/11, 'it ntf/.1f mice/21%.-

Be it known that I, HENRY B. LEAOH, of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Self- Closing Faucets, of which the following is a specification.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a longitudinal vertical section of a self-closing faucet embodying my invention. Fig. 2 is a section taken nearly at right angles to that shown in Fig. l. Fig. 3 is a view in perspective ofthe tubular neck removed. Fig. 4 is a perspective view of the washer F removed. Fig. 5 is a vertical section showing al modification. Fig. 6 is a sectional view of another modification.

This invention relates to that class of selfclosing faucets in which inclines of quick or steep pitch are used for lifting or moving a valve from its seat in connection with a spring for returning the'same to said seat after the handle has been released.

A represents the casing, A the nozzle, and a the inlet-tube.

B is the cap, provided with the handle B', adapted to turn in both directions. Madeintegral with or rigidly secured to this cap ar'e the inclines b. l

C is the tubular neck, screwed into the casing A,and provided witha base, C', resting on said casing and sustaining the cap B. This tubular neck is provided with inclines d, corresponding in pitch with the inclines b, above referred to.

D is the top screw, screwed into the handle or cap B B', and provided with the chamber D.

E is'the valvestem, K the valve-seat, G the packing, H the valve, and .I the spring. The valve-stem extends from the valve up through the tubular neck C and cap B, the head E of the same extending above the top of said cap. The valve-stem is provided with an annular groove, E, partially around which extends the washer F, of the shape shown in Fig. 4, said washer resting on the top of the cap B, and it is held in place by the top screw, D, which is provided with an annular shoulder, D, for the purpose. Said top screw is further provided with a chamber, D', sufficiently being sufficiently broad to give enough'space for lost motion between the washer F and the head of the valve-stem to allow the valve Hto be seated by the spring without said head coming in contact with the top of said washer. This arrangement also provides `a perfect swivel, so that the handles B and cap high, and thegroove E", in the valve-stem,V

B can be turned and the Valve moved from its seat without turning the valve-stem. When the handles B are turned, the inclines are moved one set upon another in such a manner that the inclines b, or those which are turned by the handle, are in such a positionwhen the valve is on its seat that their lower ends, b,' lap or extend below or beyond the bases or lower ends, d', of the inclines d, so that upon turning the handle and causingV the inclines b to move upward upon the inclines d, the points b cannot cut or grind into the inclines d, while being returned to their former position by the action of the spring. The points b of the inclines b are prevented from reaching the bases d of the inclines d by a suitable stop, the an-` nular ring I upon the valve-stem being, perhaps, preferable for that purpose.` The upper ends, b, of the inclines b are below the tops d of the inclines d, and are prevented by said stop from being moved up or past said tops. Consequently these tops d cannot cut or stick into the inclines b when said inclines are being returned by the action of the spring to their former position or resting place.

My invention applies to all self-closing faucets having threads or inclines in which the valve is moved from its seat by the motion of one set of inclines upon a corresponding set in the direction from bottom to t'op of the inclines upon which those that are turned by the handle are moved. i

In Fig. 6 an example of screw-threads in place of and operating in the same manner as the inclines above described is seen. The inclines or threads are of a sufficiently steep pitch to give way to the pressurenecessary to close the valve.

prevents dirt and grit from working in upon The top screw in the handle roof Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a faucet in which the valveis moved or lifted from its seat by means of an incline or incline or set of inclines and returned to its seat by the pressure of a spring, the inclnes b d, arranged as described, whereby when the valve is closed the points b of the turning inclines b shall extend below or beyond the points d on the inclines d, and the points d of the inclines d extend above or beyond the points b on the inclines b, in combination With a suitable stop, spring, handle, and valvestem7 substantially as and .for the purpose described.
